Andrea Michaelsson, alias Btoy, is an urban artist from Barcelona. Her vocation began in 2002. Her portraits are gazing on us and make us reflect on the passage of time. The stencil technique and sometimes paste-ups are expressing a strong nostalgic idea and are shaken with brushstrokes full of strength and contrast. She has exhibited in different cities such as Barcelona, Paris, Bergamo, London, or Jakarta and she collaborated with Banksy.
